Let's re-draw this, so it looks a little bit neater, where we have a triple bond in the middle instead, and again, we need our negative 1 charge there.
让我们重写这个，这样看起来更整洁一点，我们有一个三键在中间，同样地，我们这里需要一个负电荷。
-
Now, that rapid rise is called depolarization and the membrane is said to be in a depolarized state because it's less polarized or less negatively charged repolarized as negatively charged.
这个迅速上升过程称为去极化,我们称膜处于去极化状态,因为膜的极化程度降低了,或者说是带的负电减少了,而复极化就代表重新带上负电荷

-
We have the minus because we're adding a negative charge from the electron.

这是一个负电荷，这是一个正电荷。
-
That's not a positive and negative charge, that's actually a phase, and that arises from the wave equation.
这不是指正负电荷，它是指相位，这是从波函数中得来的。
-
So, the negatives are, these are negative.
因此，这些带负电荷的东西带负电荷。
-
And since we have two bars that are together like this, once they're both loaded up with electrons there's going to be negative charges that repel, so the electrons will want to get as far away as possible, and they're on their slow way to doing that, to getting as far away from each other as possible.
因为我们有两个棒像这样在一起，一旦它们加载了电子,就会因为有负电荷而排斥，所以这些电子就会,互相离开的尽可能远，它们的这个过程很慢，离开的尽可能远。
-
You've got negative charge in motion, and it's in a circular orbit.

你有一个正电极,电子带的是负电荷。
-
Cation is plus one, anion is minus one.
阳离子带正电荷，阴离子带负电荷。
-
It's loaded with phosphates which are negatively charged.
NA分子上有很多带负电荷的磷酸根
-
And so, there is an attractive force between the two of them, the positive and the negative.
因此这两个正负电荷间，存在一个吸引力。

This was my first glance at plum pudding, and I guess you can see that this must be that positive part -- most of the plums are within that, and you can see all these little raisins or plums in here, that would be that negative charge.
我想你们可以，看到着一定是正电部分,大部分的李子,都在这里面，你们也可以看到,这些小的葡萄干或李子，这就是负电荷。
-
So now that means if this is where the center of positive excess charge lies and on top of it is the center there is no displacement of the charge so there is no net dipole.
所以现在我们说,如果正电荷中心,就位于,那么还是在这里负电荷中心也在这里,所以没有空间偶极。
